Eight-channel microwave photonics transceiver photonic integrated circuit

【摘要】 Microwave photonics（MWP） studies the interaction between microwaves and light waves, including the generation, transmission, and processing of microwave signals. Integrated MWP using photonic integrated circuits（PICs） can achieve compact, reliable, and green implementation. However, most PICs have recently been developed that only contain one or a few devices. Here, we propose a multi-channel PIC that covers almost all devices in MWP. Our PIC integrates lasers, modulators,amplifiers, and detectors in the module, successfully manufacturing an eight-channel array transceiver module. We conducted performance tests on the encapsulated transceiver module and found that the cascaded bandwidth of the eightchannel transceiver module was greater than 40 GHz, and the spurious-free dynamic range（SFDR） of the broadband array receiver module was greater than 94 dBm · Hz^2/3. The noise figure（NF） is less than-35 d B and the link gain is greater than-26 dB. The success of multi-channel PIC marks a crucial step forward in the implementation of large-scale MWP.更多还原
